Canberra Raiders coach Ricky Stuart has questioned the NRL's interpretation of the obstruction rule, saying referees are being forced to "guess" at critical times in games.

The Raiders felt the sting of a no-try call after Junior Paulo crashed over during the second half of their stunning last-gasp 20-19 loss to the New Zealand Warriors.

Stuart said the game needs to address the issue before the outcome of more games are changed due to differing opinions.

"It should have been 25-6, because that obstruction try was a try," Stuart said.

"We have not identified what's an obstruction in this game, and I know I'll be called a whinger and a sook, but that doesn't worry me. 

"We, as a game, have not got a handle on what is an obstruction, they [refs] are guessing. I'm not blaming the referees because they don't know either, poor buggers. 

"So, I'll be waiting for Todd [Greenberg] to ring me and to tell me what an obstruction is.

"I want him to look at last week's obstruction when we lost the game over it, I want him to look at this week's obstruction where it takes to 25-6 and tell me what the difference is."

An exasperated Stuart implored NRL boss Todd Greenberg make sure there was a clear-cut ruling on what is an obstruction and what isn’t.

"Todd said not the blame the refs and I'm not, so I am looking at the instructions he's giving and the interpretations that are ruining the game at this time," he said.

Stuart's call comes a day after Canterbury Bulldogs fullback Moses Mbye was awarded a try despite replays showing Penrith's James Maloney was checked in his attempt to make a potential tackle.

For the third straight week, the Raiders held onto what could have been a match-winning lead, at one stage up 19-6, only to see it slip agonisingly through their grasp.

"We were the best team on the day and we got beaten," Stuart said.

"This past three weeks is really important to understand from our point of view with how we handle it. The way we bind together and handle this situation will make or break our season.

"So, we have to use it and grow out of it because there no other way to look at it."

Raiders captain Jarrod Croker said the side was determined to fight their way back despite losing all three games this season by a combined total of just five points.

"It's heartbreaking, it's three tight ones in a row and the boys are absolutely gutted," Croker said.

"We're sticking together because there's nobody else that can get us out of this situation but ourselves."
